I am normally up and about at 4am after having "died" at about 10:30pm the previous night. This is handy for commuting to the London Office -the 4:05am train off platform 6. It has become "normal" for me and Matthew to have a cuddle&play and for me to make him breakfast at that time. He normally goes and reads or experiments with his lego/mecanno/hornby until school time. He is normally "dead" at 8pm and that is him done -until the next morning!!!
His mother is one of those people to whom "morning" is an almost lethal experience... However she is up and about until 2am under her electric duvet cover and electric underblanket "sitting and stitching" etc!!!
